BARREL-FORMING MACHINE.

Specification of Letters Patent.

Application filed January 12, 1911.

Patented Sept. 26, 1911.

Serial No. 602,367.

To all whom it may concern:

Be it known that I, ROBERT D. KINYoN, a citizen of the United States,'residing at Chicago, in the county of Cook and State of have been used previously, but these are open to many objections on account of the difficulty of operation. The usual type of machine consists of a cable which surrounds the barrel and is operated by means of a power Windlass. By means of such a machine it is very diflicult to apply exactly the correct amount of pressure and also to keep the barrel staves in proper alinement.

In my improved machine the staves are preferably first steamed in order to render them pliable and their lower ends then placed in a retaining frame. The machlne is then started and circular formers, moving toward each other from opposite sides '7 racks and pinions.

" I of the barrel, are brought into contact with these staves, thereby keeping them in proper alinement and forcing them into the proper ositions. My machine is also, in its pre erred form, provided with a spring memher which comes in contact with the center or bilge of the barrel. The formers which come in contact with thestaves are preferably operated by means of sliding bars actuated by suitable gearing connected with vantages of my invention will be more read ily understood by reference to the accompanying drawings in which:

Figure 1 is a plan of my barrel forming machine. Fig. 2 is a side elevation of the machine shown in Fig. 1. Fig. 3 is a fragmentary vertical section showing the mechanism directly associated with forming the barrel.

Resting on the supports 10, 11, and 12 are the longitudinal frame members 13 to which are attached the upri 'hts 14 and 15, the cross member 16 extent ing between the two uprights 14 and being secured in position i by the bolts 17. The longitudinal frame These and other ad-v members 13 are preferably channel-shaped being provided with grooves 18. Supported in suitable bearings is the shaft 19 having rigidly mounted near its ends the pinions 20. These pinions engage the racks 21 and 22 which are attached to the longitudinally sliding bars 23 and 24 so that on rotation of the shaft 19 the bars 23 and 24 will be moved in opposite directions. Also mounted on shaft 19 is the gear 25 which is in mesh with pinion 26 rigidly mounted on shaft 27, the ends of which are held in suitable bearings 28. Also mounted on shaft 27 is the gear 29 in mesh with the pinion 30 on shaft 31, the ends of which are mounted in bearings 32.

Loosely mounted on shaft 31 are the pulleys 32 and 33 which are rotated in opposite directions by means of suitable belts. Cotiperating with pulley 32 is the friction cone 34, and coiiperating with pulley 33 is the friction cone 35. The cone 34 is controlled by the clutch 36 by any of the Well known methods, and the cone 35 is controlled by the clutch 37. In order to operate the clutches 36 and 37, a lever 38 is provided which is suitably connected with the handles 39 of the two clutch members 36 and 37. The lever 38 is pivoted to some suitable part of the left hand end of the machine shown in Figs. 1 and 2. The bracket 41 is secured to the bottom of one of the longitudinal frame members 13 by the pivot 40. The lever 38 terminates in the operating handle 42, and mounted on the lever is the roller 43 which is adapted to move within the slot 44 of the bracket 41. It will now be apparent that if the handle 42 is moved in a transverse direction, the lever 38 will serve to connect either the friction cone 35 with its corresponding pulley 33, or the friction cone 34 with its pulley 32. In the former case the shaft 31 will be rotated in one direction, and in the latter case in the opposite direction. As will be readily apparent to those skilled in the art, the rotary movement of the shaft 31 will be transmitted through the pinion 30, gear 29, pinion 26, and gear 25 to the shaft 19, thereby moving the sliding bar 23 in one direction or the other according to the direction of rotation of the shaft 31, and at the same time moving the sliding bar 24 in the opposite direction. On the other ends of the sliding bars 23 is mounted the cross member 45 which as clearly shown in Fig. 1 is in the form of an arc through most of its extent.

The upright supports 47 are secured to the right hand ends of the sliding bars 24. To the upper ends of these supports is bolted the cross member 48 similar to the cross member 45 but curved in the opposite direction. A controlling rod 49 is attached to one of the bars 24, as shown in Figs. 1 and 2.

Attached to the cross member 45 are the brackets 50, these being secured to the member 45 near their central portions by means of the extensions 51. These brackets are preferably inclined, as shown in Figs. 2 and 3. To the upper ends of brackets 51 is secured the curved forming member 52 by means of the rivets or bolts 53. To the lower end of the brackets is secured the semi-circular member 54, the position of which may be regulated by adjustment of the screws 54 Similar brackets 50 are attached to the cross member 48 by the extensions 51 and have secured to their upper ends the forming member 52, and to their 1 lower ends a circular member 54.

Pivotally mounted on the ends of the forming members 52 are the movable forming members 55 which have the slots 56. Mounted on the cross members 45 and 48 are the guide bolts 57 which are placed in the slots 56 and serve to direct the movement of the movable forming members 55 in a manner which will be described hereafter.

Extending through the members 54 are the pins 58 having on their ends the nuts 59. These bolts on their inner ends are provided with clamps 60 retaining the spring formers 61. Between the clamps 60 and the inner edges of the members 54 are mounted the springs 62 surrounding the pins 58. The spring formers 61 have the straight portions 63 which extend through the apertured brackets 64 mounted on the members 54. The apertures through these brackets are preferably of somewhat larger diameter than the diameter of the spring formers 61 in order to take care of slight lateral movement as will be explained here.

after.

Between the supports 11 and 12 I place the stand 65 through the center of which is the threaded aperture 66. Within this aperture the screw 67 is adapted'to operate. The screw 67 is provided with the shoulder 68 above which is placed the compression spring 69. Between compression spring 69 and the head 70 of the screw 67, is placed the base 71 preferably consisting of two plates 71 and 71 the latter of smaller di ameter than the former. Attached to the base 71 are the upright brackets 73 within which is supported near their upper ends the metallic ring or truss hoop 74. It will be evident that by turning the screw 67 the position of the base 71 may be elevated or depressed as desired. Just inside of the brackets 73 is placed the removable truss hoop 72, between which and the plate 71 is formed the annular groove 72*.

Having thus described the construction of my machine, its operation may now be understood. After the barrel staves 75 have been steamed in order to render them pliable without breaking, their lower ends are placed within the annular groove 72 in the base 71 and the staves occupy the positions shown in Fig. 2. The handle 42 is now moved inwardly so that one of the friction cones 34 engages its corresponding pulley 32, and the pinion 20 is rotated in the direction shown by the arrow in Fig. 2. As a result the bar 23 is moved toward the staves 75 and the bar 24 is moved in the opposite direction. This results in carrying both cross members 45 and 48 and their as-.

sociated parts toward the barrel staves. The bilge of the barrel is engaged by the spring formers 62 which conform to the shape of the barrel by outward pressure of the spring-controlled pins 58, the straight ends 63 of these spring formers meanwhile passing through the apertures of the brackets 64. At the same time it will be clear that the formers 52 are brought toward the barrel and the movable forming members 55 are gradually moved inwardly by the guide bolts 57 operating within the slots 56. In this way the staves are gradually forced into the positions shown in Fig. 3, and the barrel attains its finished shape. On the controlling rod 49 are mounted the collars 76 and 77 which are adapted to en gage the angle iron 78 which is mounted on the bracket 41, the rod 49 passing through a suitable aperture in the angle iron 78. It will be apparent that as the sliding bars 24 move to the left, as indicated in the drawings, the collar 76 will engage the angle iron 78 and the bracket 41 will be carried toward the left. The inner edge of the slot 44 will engage the roller 43 and the lever 38 will thus be moved outwardly, thereby disengaging the friction cone 34 from its pulley 32 when the formers have reached the position in which the barrel attains its final finished shape. In order to release the formers from the barrel, the handle 42 is moved still farther in an outward di rection causing the cone 35 to engage the pulley 33 and the pinion 20 is rotated in the opposite direction from that shown by the arrow in Fig. 2. In this way the sliding bars 23 are moved to the left and the sliding bars 24 to the right until the collar 77 engages the angle iron 78, thereby moving the bracket 41 to the right and causing the outer edge of the slot 44 to engage i the roller 43. Such engagement causes the lever 38 to be gradually moved inwardly have been until the cone 35 is disengaged from the pulley 33, the operation of the machine thereby being stopped. When the staves brought into the form of the finished barrel, a temporary truss hoop may be applied to the top of the barrel. When the formers have been released from the barrel, the latter carrying with it the truss hoop 72 to hold the barrel in its proper form may then readily be removed from the machine another truss hoop 72 is placed within the brackets 73 and new staves are placed in position.

The spring 69, above-mentioned, is provided for the purpose of giving the barrel a resilient support while it is being formed.

It will be apparent to those skilled in the art that many changes could be made in the I detailed construction of the machine which I have described without departing from the spirit and scope of my invention.
